getRelativePath

Gets the relative pathname relative to a directory

Description

Gets the relative pathname relative to a directory.

Usage

## Default S3 method:
getRelativePath(pathname, relativeTo=getwd(), caseSensitive=NULL, ...)

Arguments

pathname

A character string of the pathname to be converted into an relative pathname.
relativeTo

A character string of the reference pathname.
caseSensitive

If TRUE, the comparison is case sensitive, otherwise not. If NULL, it is decided from the relative path.
...

Not used.

Details

In case the two paths are on different file systems, for instance, C:/foo/bar/ and D:/foo/, the method returns pathname as is.

Value

Returns a character string of the relative pathname.

Non-case sensitive comparison

If caseSensitive == NULL, the relative path is used to decide if the comparison should be done in a case-sensitive mode or not. The current check is if it is a Windows path or not, that is, if the relative path starts with a device letter, then the comparison is non-case sensitive.
